Your platform knows about the incident before anyone calls anyone. One endpoint handles applicability, collectors, clocks, chain of custody and the record.
Counter methodology: no live national crash feed exists. The counter advances at the average rate implied by the most recent published annual figure (528,177 ÷ 365 ≈ 1,447 per day ≈ one every 0 seconds), reset at midnight local time. It is an estimate for illustration, not a report of specific incidents, and is updated when federal agencies publish new annual data.
